Vishay ESTA
Power Electronic, DC Capacitors
STANDARD CAPACITORS IN CYLINDRICAL CASING, OIL IMPREGNATED, SELF-HEALING, WITH FUSE
DC CAPACITORS
Series GMKP 1000V - 3000V, higher voltages upon
request.
NUMBER OF DISCHARGES
upon request
Capacitance range 1-400µF, in relation to rated
voltage and dimension. Other capacitance values,
upon request.
TIME INTERVAL BETWEEN 2 DISCHARGES
With a periodic discharge: 2 sec.
With oscillating discharge: upon request
GENERAL
TERMINALS
VISHAY ESTA DC-capacitors may be loaded with a
comparatively high component of alternating voltage or
alternating current due to the low ohmic and low dielectric
losses. Thus the capacitors can equally be employed for all
DC applications.
AMP plugs 6.3 x 0.8 or
Threaded bolts M10
MOUNTING POSITION
vertical/horizontal
upside down position, upon request only
The capacitors can also be applied as AC capacitors at a
rated frequency of 50 Hz for the quoted root-mean-square
voltages.
